Purpose
The tensile force required to produce a rupture in a strip of paperboard, measured in MD & CD, expressed in kN/m. Tensile strength is indicative of fiber strength, fiber bonding and fiber length. Tensile strength can be used as a potential indicator of resistance to web breaking during printing or converting.
| Grade (typical Tensile index value) | MD (Nm/g) | CD (Nm/g) |
| Newsprint (40 - 49 g/m2) Stationery (50 -100 g/m2) Tracing Paper (60 – 110 g/m2) Test liner (186 g/m2) | 45 – 60 40 – 70 70 175 | - 20 – 40 40 80 |
How to use
The piece of the example test that will be tested with the measurement 25mm x 15mm (8 examples of the test)
Put on all the tips of the sample test in upper and pay attention to so that the straight fitting/not askew and tightened the screw
Loosened clipper the attraction
For the testing, put one by one on the sample test in clipper low and tightened the screw
Open the pendulum lock
Press the switch start to run the pendulum
The stopping swing at the time of paper was cut off
Press the switch stopped and return to return in the beginning position. Repeated the testing’s sample that was provided
